Thanks very much, Scook.
This all worked perfectly, but it was quite a bit of a learning curve. I had no idea what dot CAL files were, but found the folder where they are stored. Looked at a few, but it is rocket science to me. Using Notepad, I copied your scripts and named them. I had to study up on Key Bindings also. Did not know it was there under Options. Bound the CALs to Left and Right keys and it works great.
I had to change (+= Now 30) and (int offset 30) to (+= Now 2) and (int offset 2) to get the Now bar to step in 1 milliseconds increments.
